Form guide: United start the festive fixture programme of four Barclays Premier League outings in a week-and-a-half having won the last three games across three competitions. The defensive unit has excelled during this good run, keeping clean sheets in the wins over Shakhtar Donetsk, Aston Villa and Stoke City. The Hammers have won just once in their last eight league matches, but the stirring late comeback that knocked Tottenham out of the Capital One Cup on Wednesday will have provided a welcome boost. That said, the east London outfit have failed to score in their last five visits to Old Trafford.
Ins and outs: Wayne Rooney missed Wednesday’s win over Stoke, but David Moyes said the striker “has got a chance” of recovering from his groin injury in time for Saturday. Robin van Persie is out until early January with a thigh injury, but while Michael Carrick is nearing a return to contention the visit of his former club may be too early for the midfielder. West Ham and England striker Andy Carroll is still out with the foot injury that has prevented him from appearing all season, while defender Winston Reid is also absent following ankle surgery. Skipper Kevin Nolan is serving a three-game ban for a red card he received in the recent 4-1 defeat to Liverpool.
